The sensor: a top fitting, a quarter inch, every hour
A LeaseSight tank level monitor screws into a 2- or 3-inch fitting on top of the tank and reads the fluid level to the quarter inch, every hour. There's no wiring to run across the tanks and no power source to trench in — each sensor runs on two standard AA batteries.
Every reading is stored, so you build real history instead of a daily snapshot. Each tank's page shows the trend chart and every measurement before it, and sensor tanks and hand-gauged tanks live in one place.
How a reading gets from the tank to your phone
The sensors talk to a gateway on the pad. Each sensor sits up to 75 feet from it — which covers most tank batteries from a single spot — and the gateway carries the readings out over LTE. It runs off solar, so there's no power to run out to it either.
The gateway needs a workable cell signal, not a strong one. We check coverage with you before we quote anything, so you're never sold hardware that can't phone home.

Four thresholds per tank, and an alert with the trend attached
Every tank carries four thresholds — low, critical low, high, critical high — so the same sensor watches for a tank running away and a tank running dry. Set them from your phone, or call us and we'll walk through them with you.
Cross one and it's a push notification on your phone within the hour. The alert text includes the trend, so you read something like "12 in from top (was 16 an hour ago)" and know whether you're driving out now or after coffee. Tap it and you're on that tank's page, level and trend in front of you.
Why hourly
An hourly reading catches a filling tank while there's still headspace — and a well that quit, the same morning. Reading more often than that mostly adds noise, and spends battery doing it. Hourly is the point where you find out in time to act, on hardware that keeps working between visits.
What it looks like at 2 a.m.
A water tank crosses critical high — 12 inches from top and climbing. With hourly readings, that's a push alert while there's still headspace: call the tank truck, switch the tank, go back to bed. Without them, it's whatever your pumper finds on Monday — oil past the firewall, a tank truck, remediation, and a landowner call you didn't want to make.
Batteries, signal, and a sensor that never just goes quiet
A set of two AA batteries lasts 6+ months (actual life varies with temperature and reporting frequency), and the app watches the charge for you: a low-battery warning fires at 15% and a critical alert at 5%. When it does, you can pick up batteries at any store, and a Phillips screwdriver is the only tool you'll need to swap them out.
Every device also reports its own health with every check-in — battery percentage, signal strength, and when it last called home. Low-battery and missed-check-in alerts are on by default, so a sensor that stops reporting becomes a push notification, not a blind spot you discover weeks later.
Installing it yourself
Most operators do it themselves. Tank monitors screw into the top fitting, the gateway goes up to 75 feet away, and once a sensor is on it checks in through the gateway and the first reading lands in your app — no pairing ritual, no laptop on the tailgate. If you can tighten fittings, you can install a LeaseSight sensor.
Rather have it done? In the Illinois Basin, professional installation is available at an hourly rate — we'll come to the lease, install everything, and set your thresholds with you.
Hand gauging still fits
LeaseSight works alongside hand gauging, not against it. Hand-gauged measurements, run tickets, pressure readings, and flow meter readings live in the same app — gauges entered in feet, inches, and quarters. On a monitored tank, an occasional hand gauge is just a calibration check against the sensor, and you keep gauging the rest of the battery the way you always have.
Where it's available
LeaseSight serves oil & gas operators anywhere in the US: we ship the sensors to you, and you install them yourself in minutes. Call or text and you reach a person who knows what a tank battery looks like, not a ticket queue. We're based in the Illinois Basin — Illinois, Indiana, and western Kentucky — where professional installation is available too, and we're signing local certified partners in more basins.
